LIQUID-SERVER.

Specification of Letters Patent.

Application filed November 7, 1908. Serial No. 461,538.

To all whom it may concern-.-

Be it known that I, EDWARD S. BACKMAN, a citizen of the United States,and a resident of the city of Malden, in the county of Middlescx andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Liquid-Servers, of which the following is aspecification.

This invention has for its object the citeding of certainimprovementshereinafter set forth in deviccsfor serving liquids, andespecially liquid soap, in small quantitiesinto the hand of the ersonoperating the same.

Referring to 516 drawings forming part of this specification, Figure 1is a central i vertical section of a liquid server made in accordancewith my invention. Fig. 2 is a perspective view of the serving plungerthereof. Fig. 3 is a horizontal section on the line XX in Fig. 1. Fig. 4is a similar section on the line YY in Fig. 1.

The receptacle 1 for containing the liquid to be dispensed or served ispreferably composed of glass, in order to show at a glance the quantityremaining therein; and this.

receptacle or holder is illustrated in Fig. 1 as supported by a bracket2 projecting from a vertical surface, but any other form of support maybe employed provided it leaves the under part free for the deliverymechanism. Fixed liquid-tight in the otherwise open but contractedbottom of said holder 1, is a small cylinder 3 held in place by aShoulder -l, yielding washer 5 and nut 6 on the threaded upper sectionof said cylinder. \Vithin this cylinder and slidably but snugly fittingit, is a plunger 7 from whose lower end projects a stem 8 slidable in anopening in the lower end of said cylinder. lrans- Versely through saidplunger, but preferably at a slight angle as illustrated, is an opening9 the size of which is designed to equal the quantity of liquid to beserved. When the plunger is pressed upward, as by means of its stem,until said opening 9 rises above the edge of the cylinder, the liquidwithin the holderimmeiliatclyiillssuchopening. Then, as the plunger ismoved downward to its lower limit, such liquid is carried in the openingand discharged into the spout 10 formed at one side of the lower part ofthe cylinder.

The relative positions of the spout and stem is such that theapplication of the palm of the hand to the stem and the actuation of theplunger, delivers the discharged soap into such palma A button or flathead 11 1s fixed to the extremity of said stem for the purpose ofkeeping the stem from hurting the hand, and also to serve as an abutmentfor the spiral spring 12 located about the stem, b means of which theplunger is returned wall more certainty and promptness to its lowermostposition.

To insure that there shall be no leakage from the holder between thesides of the plunger and the interior of the cylinder, I prefer toprovide the upper end of the plunger with an overhanging shoulderconsisting of a yieldingwasher. 13 held in place by a rigid washer 14and a small screw 15 ta ped into the plunger. 'hen the latter is in itslowermost position, its spring 12 presses said yielding washer 13tightly upon the u per edge of the cylinder and renders all lea ageimpossible.

Inasmuch as the spout 10 opens from one side alone of the cylinder 3, itis necessary for the plunger to be kept from turningand l therebykeeping the fluid in the openin 9 from discharging to said spout. For tis purpose, the stem 8 is formed with a longitudinal groove or spline 16into which a small spur of metal 17 is forced from that of thesurrounding cylinder-bottomf Said opening is inclined as shown in Fig. 1for the purpose of aiding its fillin and discharge. I

To keep the liquid from leaking down about the stem 8, I form the holethrough which it asses, with a flange or dike 19 ms- 1 ing a slig 1tdistance as shown in Fig. 1, and provide the plunger with a dependinapron 2O overhanging said dike. Hence Whatever liquid drips from theplunger is made to fall l spout, but it cannot reach the stem.

l The cap or cover for the open top of the l holder is held in place bythe spring fingers l 21 entering such opening.

| What I claim as my invention and for l which I desire Letters Patentis as follows, to

wit

1. A liquid server comprising a holder, a cylinder communicating at oneend with the i lower part of said holder and having a lateral Idischarge exterior to the holder, a plunger slidable in said cylinderhaving external l means for its operation and formed with a transverseopening near its lower end, and

means held by the upper end of the plunger ASSIGNOR T0 STANLEY LIQUDJSOAP 00H- Patented Aug. 24, 1909.

outside such dike and thence down to the 15 vertical cylinder open atits upper end and depending through the bottom for insuring closure ofthe upper end of said cylinder when the plunger is in itslowermostposition. i

2. A liquid server comprising a holder, a vertical cylinder open at itsupper end and depending through the bottom 0 said holder, a downwardlydirected spout o ening laterally from the lower art of sai cglinder, aplunger slidable in said cylinder an having a stem projecting throughthe lower end of said cylinder, said plunger being formed with a lateralopening near its lower end and a ring acting on said stem to depresssaid 1 iilunger.

3. A liquid server comprising a holder, a

said holder, an apertured plunger slidable in said cylinder,

' a discharge at the lower part of said cylinder,

' of said cylinder carried by said plunger, an

resilient means pressing said plunger downa yielding washer overhan theu per end ward, and means for raising said plunger.

4. A liquid server comprising a holder, a

vertical cylinder commumcating at its upper end with said holder and aspout leading laterally from the lower (part ofsaid cylinder, a

plunger slidable in sai cylinder and having a transverse slightlyinclined opening through it near its lower end, and means for movingsaid plunger. 5. A li uid server comprising a holder, a verticalc inder,a plunger slidable insaid cyl-. inder an adapted to receive liquid fromthe holder, a stem projecting from said plunger through the lower end.ofsaid cylinder for the operation of-said plunger, anda spring fordepressing said stem and plunger, the

0 enin fin the bottom of said cylinder t roug which said stem slidesbeing surrounded with a dike, said plunger being formed with anoverhanging apron or skirt.

n testimony that Iclaim the foregoing invention, I. have hereunto set myhand this d 5th day of November, 1908.
